SPECIFICATION forming part of Letters Patent No. 707,725, dated August26, 1902.

Application tiled April 20, 1900. Serial No. 13.577. (No model.) i

T @ZZ 'za/tom, it may concern.-

Be it known that I, ALEXANDER THEODOR SARFERT, asubjectot` the King ofSaxony, and a resident of Chemnitz,'SaXony, German Empire, have inventedcertain new and useful Improvements in Cloth-Steaming Machines, of whichthe following is a specification.

This invention relates to improvements in that class of machines shownand described 1o in my application for Letters Patent liled January 20,1898, Serial No. 667,336, said improvements including some shown but notclaimcdin said application, Serial No. 667,336, and others which are forthe first time shown I5 in the present application.

In my Patent No. 516.945 I showed two forms of steaming-cylinder, eachof which presented the broadly novel combination, with the perforatedshell and steaming-steam zo supply, of a heater or heat-radiator withinsaid shell to obviate the presence in thev steaming-steam of water ofcondensation. In both of said forms of steaming-cylinder, however, themeans for handling the steam within z5 the cylinder were simple passagesdevoid of steam-chambers. For this reason and also because of theirrelationship said passages were lacking in the efliciency attainablebyof the steam-passages for introducing the steaming and heating steaminto the cylinder and for handling the same within the cylinder, so asto efficiently apply the heat to the steaming-steam to prevent formationof water of condensation.

Other features consist in the arrangement of the steam-passages so as tomore eificiently 5o separate the Water of condensation from the4driving-gears of the cylinders. front view of said driving-gears.

steaming-steam and submit it to heat after such separation.

Other features consist in'so constructing the body or core as to enableit to constitute substantially the whole heater of the cylin- 5 5 der,and thus enable the steam-coil of my Patent No. 516,945 to be dispensedwith, if desired.

Other features, not only of the cylinder it- Self, but of thecombination in which it is 6o placed, will be evident from the followingdescription.

In the accompanying drawings, Figure l represents a verticallongitudinal section, broken away adjacent to the middle, of asteam-cylinder such as I prefer to employ in my machine. Fig. 2 is across-section of the same on the line a b of Fig. l. Fig. 3 is across-section of the cylinder on the line c d of Fig. 1. Fig. 4 is a topView of the steam- 7o ing-cylinder, partially broken away to show theparts contained. Fig. 5 is an elevation of the side of the machinecontaining the v Fig. 6 is a Fig. 7 is a 75 plan View of saiddriving-gears with the upper part of the frames broken away. Fig. 8 isan elevation of the opposite end of the machine, showing thepressure-actuating mechanism. Fig. 9 is a vertical section showing 8osaid pressure-actuating mechanism. Fig. l0 is a sectional plan View ofsaid pressure-actuating mechanism.

l is the frame of the machine, cach end of Whichcontains a cross-piece2, upon which is mounted a support 3, leaving an opening 5 to beoccupied by parts connected with the drum. i,

4 and 6 are bearings supporting two steam cylinders 7 and 8, each ofwhich cylinders is 9o constructed as shown in Figs. l, 2, 3, and 4.

9 is a hollow steam-heated pressing-drum, the bearings for which, 9a,are mounted in the forks of hangers ll and rest on the frames 2. One ofthese hangers ll is suspended at each end of the machine from the shaftl2, journaled in the supports 3 3. Both ofthe hangers ll are keyed tosaid shaft, so that they are obliged to swing in unison. The journals ofthe steaming-cylinders 7 and S and drum 9 10o are arranged insubstantially the same horizontal plane. Steam may be supplied to theinterior of the drum 9 through one of its journals.

The drum 9 is moved either toward the cylinder 7 or toward the cylinder8 for producing pressure by the following mechanism: Upon the lower endsof the hangers 11 are fixed curved racks 13, the curvature of which isconcentric with the shaft 12. The pinions 14 14, Figs. 6, 8, and 9, gearwith said racks, respectively, and are fixed on the shaft 15, whichshaft is driven bya spur-wheel16, Figs. 9 and 10, gearing with thepinions 17 and 18, which are free to revolve on the shafts 19 and 20.Duplicate mechanisms are employed for driving the shafts 19 and 2O inopposite directions as follows, a description of one being sufficientfor a description of both:

21, Fig. 10, is a clutch member fixed to the pinion 18.

22 is a coperating clutch member fixed to the shaft 2O and adapted to beshifted into and out of engagement with the clutch member 21 by thelever 23.

24 is a reel fixed to the shaft 20, upon which is coiled a rope 25, tothe opposite end of which is suspended a weight in such manner thatthese weights tend to turn the shafts 19 and 20 in the directionsindicated by the arrows 26 and 27 in Fig. 8.

28 is a ratchet-wheel fixed to the shaft 2 0 and which cooperates with adog upon the under side of lever 30 to preven't the weight from turningthe shaft, excepting when the attendantraisessaidlever30.31isasprocketwheel fixed to said shaft 2O and connected by thesprocket-chain 32 with a sprocketwheel 33, which is turned by thehand-crank 34detachably connected with said sprocketwheel 33 bythe pin35. The clutch-levers 23 and 23, by which the clutches on the shafts 20and 19, respectively, are shifted, are connected together assubstantially one lever and pivoted in the middle at 29, so that theopening of one clutch necessitates the closing ot' the other. Each ofthe weights constitutes in substance a pressure-motor, which motors theattendant winds up whenever required by turning the cranks 34. Theattendant may apply the power of either of these motors to theproduction of pressure by moving the lever 23 23 so as to throw theproper clutch into engagement, then lifting one of the levers 30 so asto disengage it from the ratchet 28, whereupon the descent of the weightwill press the drum 9 either toward the cylinder 8 or the cylinder 7, asthe case may be.

Duplicate mechanisms are employed for rotating the steam-cylinders 7'and 8, respectively, so that a description of one rotating mechanismwill answer for both, as follows: To the steaming-cylinder 7 is fixed aspurwheel 36, Figs. 5 and 6, gearing with a pinion 37, fixed to theshaft 38. Loose on said shaft is a spur-wheel 39, carrying a clutchmember 40, Figs. 6 and 7, engaging with another clutch member 41,splined to the shaft 38 and shifted by the hand-lever 42. The spur-wheel39 gears with the pinion 43, fast on the shaft 44, which shaft carriesthe fast and loose driving-pulleys 45 and 46 of the machine. The twoshifting-levers 42 and 42 are fixed to the shafts 47 and 47, which aregeared together by the gears 48 and 48, so that the shifting of eitherclutch into engagement necessitates the shifting of the other out ofengagement. The power from the shaft 44 is transmitted to the spur-wheel39 through an additional pinion 43, so as to cause the correspondingspur-wheels 39 and 39 of the two cylinder-rotating mechanisms to rotatein the proper relative directions for producing the alternate rotationof the steamingcylinders 7 and 8 in the directions indicated by thearrows 49 and 50 of Fig. 5. lt will thus be seen that when the attendantshifts the levers 42 42 iu one direction the cylinder 7 will be forcedto rotate in the direction of the arrow 49, while the cylinder 8 will befree to rotate in a direction opposite to the arrow 50, and, vice versa,when the attendant shifts the levers 42 42 in the opposite direction thecylinder 8 will be forced to rot-ate in the direction of the arrow 50,and the cylinder 7 will be free to rotate in a direction opposite to thearrow 49.

5l and 51 are beams upon which separate pieces of cloth may be rolled.Each of these beams is connected with the cylinder-rotating mechanism asfollows:

52, Fig. 6, is a stock in which one end of the beam 51 is fixed andwhich stock is fixed to a shaft 53, upon which the sprocket-wheel 54 isheld between the friction-disks 57 and 58. A chain 55 drives thesprocket-wheel 54 from the sprocket-wheel 56, fixed to the shaft 38.Thus each cloth-beam is so operatively connected with thatsteaming-cylinder which operates upon. its cloth that the cloth-beam isdriven in the opposite direction to that in which the steaming-cylindermoves, and thus the cloth as it is unwound from its steamingvcylinder iswound upon its beam, and vice versa. The size of the connecting-gears ofthe sprockets is such that the surface speeds of the steamer and beamare approximately equal; but to provide against inequalities due to thespiral winding of the cloth I place the sprocket-wheel 54 upon the shaft53 between two friction-disks 57 and 58,which are pressed together bythe thumb screw 59, acting through the spring GO.

61 is an apron of steam-pervious material, one end of which is securedto the steamingcylinder 7 and the other end to the steamingcylinder8.Between saidcylindersthisapron passes over the heated drum 9, the heatedsurface of which acts to dry the apron. This apron is of such lengththat when it is wound with a piece of cloth on either of the cylindersit is long enough to form several laps between the cloth and theperforated surface of IOO IIO

the cylinder and then extend spirally the length of the cloth around thecylinder and then extend over the drum 9 to and aroundtheoppositesteaming-cylinder. Itisnot necessary that the pressing-dru m9 be heated in all cases, as on certain goods the apron can be used toadvantage by leaving in it the natural dampness resulting from thesteaming it gets on cylinders 7 and 8. It is not necessary in that casethat drum 9 shall be made of metal. It can be made of Wood or othercheap material.

I will next describe the construction of steaming-cylinder that I preferto employ and Which is shown in detail in Figs. 1, 2, 3, and 4. Itcontains a perforated shell and inside ot' the same a steam-discharger71, a heatradiator 72, and a water-of-condensation shield 9G. Theperforated cylindrical shell 7 O is held at each end between the collars74 and 75. The collars 75 t onto the ends of the casting 72, whichconstitutes the body of the cylinderand which is cylindrical in form,with internal steam-chambers 77 and 77a open at both ends at the axis ofthe casting and preferably With external radially-extending flanges 76.78 is a web or diaphragm cast between the steam-chambers 77 77 at anydesired position therein, in which are placed the steam-chamber 79 andthe transverse passages 71 71 for the steaming-steam, anked by thelongitudinal passages 77h 771. Although I have shown the heat-radiatingmembers 76 as integral with the body 72 and the heatingsteam as passingdirect from the chamber 77 to the chamber 77a ofthe body 72 through thepassages 77b in the cross-diaphragm 78, it is evident that thisconstruction may be varied in its details Without essentially changingthe character of the device or the principles involved. 8O and 81 arecaps cast in the form shown and provided with the central passages 82and 83, which respectively register with the openings at the oppositeends of the steamchamber 77. The stationary pipe 84 leads from thesteam-supply pipe 85 into the passage 82, and a pipe 86 leads from thechamber 77";L through the passage 83 to an escapepipe 87. The mouth ofsaid pipe 86 is located near the bottom of the chamber 77a, 4so as toremove the water of condensation from said chamber. 88 is a stuffing-boxbetween the stationary pipe Si and the rotating cap 80, and 89 is astuffing-box between the stationary pipe 86 and the rotating cap 81.Steam under high tension enters the steam-chamber 77 77 through thepipes 85 and 84 and escapes from said steam-chamber through the pipes 86and 87, so as to maint-ain the radiator-casting 72 at a hightemperature. 90 is a pipe rotating with the radiator-casting and whichextends from the steam-supply pipe 91, concentric With the axis ofrotation, to the passage 79, being fixed to the web 78. 92 is astuffing-box through which the pipe passes, and 93 is a stufng-boxthrough which the pipe 91 passes. Steam under lower tension than thatsupplied to the steam-chamber 77 passes from the pipe 91 through thepipe 90 and the passages 79 and 71 and is discharged from the passages79 and 71 into one of the annular spaces 94 between the iianges of theradiator, from which it passes into the spaces successively between theother ilanges through the grooves 95 in the peripheries of the iianges,so as to fill all the space inside of the cylindrical Water-shield 96.While in this space this steam is held closely in contact with thesurfaces of the radiator, which are maintained at a relatively hightemperature by reason of the relatively high tension of the steamcontained within the steam-chamber 77 of the radiator. Into some of thegrooves 95 in the peripheries of the radiator-anges tit correspondingdepressions in the shield 96, as shown in Figs, 2 and In the spaces madeby these depressions are placed the longitudinal pipes 98 982L and 9999, the ends of Which are turned inwardly at 100 toward the center ofthe cylinder and project through the shield 96 into the space occupiedby the steam next the radiator. The pipes 98 98a and 99 99iL areperforated at 101 from end to end. The steam discharged from thepassages 71 after passing in succession through the spaces 94 enters themouths 100 of the pipes 98 98"L and 99 99a and is discharged from thesepipes through the perforations 101, Fig. 4. It then further distributesitself through the annular space 102 and nally escapes through theperforations in the shell 70 and through the apron surrounding the sameinto and through the successive laps of cloth and apron Wound upon thecylinder. The bent mouths 100 of the pipe 98 98aand 99 992L projectsuliiciently inside of the Water-shield 96 to take the steam from aposition in the space 94 close to the radiator-surface, and thereforethey take the driest portion of said steam, leaving any Water ofcondensation trapped by said Water-shield 96, where it is subjected to aheat from the radiator, which in the continued use of the machine Willrecouvert it into steam. By the construction of the cylinder describedit will be observed that the steam which is emitted from the perforatedshellin passing through the cylinderis so conducted and held withrespect to the radiator and the water-shield as to be thoroughly driedand free from Water of condensation.

In the construction above described, and shown in Figs. 1 and 2, it willbe observed that the radiator and Water-shield and steamdistributers 9898a and 99 99 are fixed to and rotate with the perforated shell 70. Thesteam-supply pipes 85 and 91 by the use of a reducing-valve on one maydraw their supply from a common main.

106 and 107 are valves by Which the supply of steam to the pipes 85 and91, respectively, is controlled.

The idea of employing a steam-chamber (as, for example, in the course ofthe heatingsteam through the cylinder) enables me by devising` efficientform, size, and location IOO IIO

, of the shell.

thereof to regulate the amount and distribution of the heat within thecylinder to the extent desired. In the form shown in the accompanyingdrawings the steam-chamber 77 77, which may be regarded either as asingle or as a duplex chamber, extends at 82 and 83 into the heads orcaps of the cylinder, so as to heat the same and prevent them fromwithdrawing the heat from the spaces within the cylinder occupied by thesteaming-steam. Said steam-chamber 77 '77aM is also shown as of adiameter at least one-third the internal diameter of the shell, and ifmade of these proportions it is capable of containing a sufficient bodyof steam to supply the necessary heat for the entire space within theshell, so as to enable the constructor to dispense, if desired, with thesteam-coil shown in my said Patent No. 516,945. The external diameter ofthe body or core 72 if made, as shown in the drawings, more thantwo-thirds the internal diameter of the shell will conduct the heat fromthe body of steam within the steam-,chamber 77 77:L into close proximityto the interior of the shell, and thus maintain the requisitetemperature in the annular film of steaming-steam passing to theperforations Since according to the proportions shown in the drawingsfor acylinder one foot in external diameter the annular space betweenthe exterior of the core or body and the interior of the shell will beonly about one inch in thickness, the longitudinal steaming-steampassages 98, 98a, 99, 99a, and 95 are accommodated without increasingthe thickness of said annular space by placing said longitudinalpassages, as shown, in depressions in the surface of said body or core-The dimensions above referred to are at. tained, as shown in thedrawings, without necessitating the enlargement of the journals of thecylinder, which are shown as less in diameter than` the core or body 72or even than the steam-chamber 77 77a. Not only does the idea ofemploying a steam-chamber within the shell enable the constructor toefficiently maintain the temperature of the steaming-steam while it ispassing in the annular spacebetween the core and the shell, as abovedescribed, but it also enables the constructor to efficiently maintainthe temperature of the steaming-steam on its way through the cylinder tosaid space. Thus, as shown in the drawings, the steaming-steam from itspoint of entrance into said cylinder may be led along a chamberedportion of said core, (preferably through one of the chambers itself,)so as to subject the steaming-steam to the heat of said chamber.Moreover, the employment of the steam-chamber 79 enables thesteaming-steam to be temporarily held, if desired, in a position whereinit is subject to the heat from both the chambers 77 and 772i, afterwhich it is trapped by the inwardly-projecting nozzles 100 while stillheld in con tact with the core within the passages 94, which act as apreliminary-expansion chamber for the steaming-steam preparatory to itsfinal expansion after it passes out of the pipes 98 981L and 99 and 99a.At the pointin the chamber 79 where the distribution of thesteamingsteam begins it is thoroughly subject to the heat of theadjacent steam-chambers. When the distribution commences, therefore, theheating-steam is not only thus fortified against the formation of waterof condensation, butit starts from substantially the middle of thecylinder, so as to insure a substantially equable distribution oftemperature of the steam emitted at different parts of the perforatedshell. The steam thus starting under the best conditions is firstdivided into two parts by the two discharge-passages 7l 7l, whichdeliver it from opposite sides of the core into the passage 94. Hereeach half of the steam is again divided into substantially two parts,which How, respectively, toward the opposite ends of the cylinder, eachpart being subject to substantially the same conditions and each partbeing again subdivided by the perforated pipes 98 9S 99 99a.

Although I have above described with minuteness of detail the variousfeatures of the construction shown in the accompanying drawings, I amwell aware that many of these details may be omitted without departingfrom my invention, and I therefore do not wish my description to betaken as indicating an intention to limit myself to the same.

Although I have shown the journals,heater, and steam-passages asrotating with the perforated shell instead of being stationary, I do notwish to limit this patent to this feature.
